Throwing this out there--- I am currently completing a fairly large meta-analysis on a subject closely related to the work my lab is doing. My mentor has agreed to be senior author on the paper, to double check my data analysis, and to edit/revise the manuscript. Mind you, most of the work I'm doing is being done independently, on my own time (it's a lot of time expended in the context of working full time...). To be fair, I have helped to publish a meta-analysis in the past, so I know what I'm doing for the most part, and I am comfortable using statistical software. However, I definitely don't think that completing a meta-analysis is above anyone's head. Meta-analyses are nothing to write home as far as use of creative energy goes, but it serves its purpose in terms of showing dedication, perseverance, and a willingness to be busy
